The number of + in leukocytes and epithelial cells indicates how much inflammation is present. 2 + epithelial cells and 1 + leukocytes indicate mild inflammation. Epithelial cells > 2-3 + and leukocytes < 1 + are normal. Epithelial cells are cells that are normally shed, while leukocytosis is often caused by infectious diseases, and 2 + leukocytes is not much. White blood cells are the body's defense cells, which can reflect the severity of the infection from the side.
